Application filed October 6, 190B. Serial No. 521,267.

To all whom it may concern.' l

Beit known that I, HAROLD D. WATER. HOUSE, a citizen of the United States, residing at. Quincy, county of Norfolk, and State of Massachuecttsj have invented an 1in-- provementin (lasolene-Strainers, of which the following description ,in connection 'with the accompanying drawing, is a. Specification. like characters on the drawing representing like parts.

' This `invention relateato gasolenestrainers adapted tobe inserted in a line of pipe es pecially adapted to be used in connection with gaaolene or other hydrocarbon engines.

The object of the invention is to provide a simple and inexpensive Strainer which Awill not only strain out and prevent the Vpassfqfre to the delivery pipe of any solid foreign matter,A but which will also separate from the gasolcne any water which may be mixed therewith.

The novel features of the invention will be more fully hereinafter described and then pointed out. in the appended claims.

Referring now to the dra wings, Figure 1 Vis a side View of a strainer embodying my invention; Fig. i. is a section on the line -w, Fig. 1; 3 is a top plan View of the strainer; Fig. 4l is a section on the line 1/- 1/, Fig: 2; Fig. 5 is a detail showing the manner in which the strainer is held in place.

The deiriee as herein shown coniprises an 0pen-top]: edy cup-Shaped body constituting a settling chamber, a cap fitted to the body and having inlet and outlet ports leading to said chambeigan'd a strainer situated'to intcrsect. the flow from the inlet to the outlet port land to `rstrain the gasoleue passing through the device.

The opcntop`ped cup-shaped body is designated 3 and the cap is designated 4. Said cap is provided with the interiorly screw'- threadrd flange or apron 5 which Screws over the upper screw-threaded end (3 of the body 5l? the latter preferably havingthe hex- --agonal portion 7 thereonV to permita wrench to be applied thereto for screwing` it into cap or unscrewinglr it therefrom. Said cap is also formed with the central discharge chamber 8 which communicates withthe chamber 9 in the body B andwhich also oommunicatcs with an outlet port 10 to Which a.Y Suitable discharge pipeA 11 may be secured in 4the any suitable way. 'The cent-ral discharge chamber 8 is Surrounded by an annular wall 12 which is situated within and is spaced from the outside or exterior wall of the cap whereby an annular inlet chamber 13 is provided7 said chanxber also opening into `the settling chamber 9 and communicating with an inlet port 14 to which an inlet pipe 15'is connected.

' The strainer is shown at 1G and it may be of any suitable material, but preferably is a fine wire gauze. I have alitown the strainer as cone-shaped, but this 'particular shape is not essential to the invention. For securing the strainer in position I have provided it with a holder in the' form of a, flange 17 which extends outwardly'therefrom and to which the strainer is Secured. This dan e-is adapted to rest against the lower edge o i the :Wall 12 and the edge of it is clamped between an annular-shoulder 18 with which the gap 4 is provided andthe top edge 19 of oel-y 3, as clearly Seen in Fig-2. 4Said flange is provided with a plurality of apertures 20' which are in alinement with the' inlet chamber 13 and which provide for free communication between said chamber and the Settling chamber 9. l wilhpreferably make the lower edge o'f the wall ,12 to extend slightly below the .shoulder 18, as best. seen in Fig. 5, so that when the pariset-ire assembled and the body'-l ie screwed tightly into the cap, thev flange 17 will be sprung or bent over the wall 12 and thus a perfectly tight joint will be secured between Said flange and the wall.

lVhcn my Improved strainer is in operation, the gasolene is admitted through the port 14, fills the inlet chamber 13 land'then is,delivercd down through the apertures 2Q 1n an annularsheet which'tlows down overt' 'the inner wall of the body 3. The gasolerie passes upwardly through the strainer 1G and y out. through thhxcerftral)discharge 'chamber 8, ae will be obf-noufs. By having the gaanlene admitted through an annular inlet` chamber l'which is adjacent the wall 0f thev settling chamber, the fiow of gasolene will be inwardly from all sides of the'settling chamber and thus the entire surface of the conical strainer will be effective in straining gasolene.

By using a conical strainer a large strairr ing surface is provided relative to the size of the strainer and by providing foradmit-ting t'hb gasolene to the settling chamber withA a body constitutin 9 in an annular sheet which .surrounds the ber, of a ca for the b( Y central disc arge chamber communicating 3o said inlet chamber communicaing with .the

,cap

with the settling chamber and alsowith an annular inlet `chamber r at sur rounds the discharge chamber and is separated therefrom by a wall, said inlet .chamber communicating with the vsettling cham-- ber near the periphery thereof, a conical strainer` between the inlet chamber and the discharge chamber, and a holder for the strainer clamped between the body and the strainerrthe combination with a body constituting@ settling chamber, of a capscrewed to the' ody and provided with a central discharge chamber communieating with the settling chamber and also Y 2. Ina. gasolene .provided with an annu ar inlet'chamber sepav `rated vfrom the discharge chamber by a wall,

y .provided with rovidedy settling chamber, said cap yalso havin 1 anu-annular shoulder exterior to the inlet c amber,'

and. a Astrainer having a perforatedflange resting agamst the lower edge oi said wall and clamped between said shoulder and the top of the `bod 3. 'In a gasohane strainer, the combination with a body constituting a se'ttlin chamber, of a cap screwed to the body' an provided with a central eating with the settling chamber and also provided hwith an annular' inlet chamber separated from the discharge chamber by a wall, said inlet chamber communicating discharge chamber communiwith the settlingchambe'r, said cap also having an annular shoulder exterior to the 'inlet chamber, and a strainer having a perforated ilange resting against the lower edge of said -wall and clamped between said shoulder and the top of the body, the lower edge of said wall bein shoulder whereby the ange 1s sprung over the wall.

In testimony whereof7 I have signed my name to this speciication, in the presence of two subscribing witnesses.
